[CentOS] usb 1-2: device not accepting address 2, error -71 - CENTOS 5

Hi all,

I installed CentOS 5 on DELL machine. Then, When the system comes up, I always get below erros.

Could you pls help me to solve this out before I setup this box for productiuon use ?

these are errors.

usb 1-2: device not accepting address 2, error -71 ata2: port failed to respond (30 secs) ata2: SRST failed (status 0xFF) ata2: SRST failed (err_mask=0x100) ata2: SRST failed (status 0xFF) ata2: SRST failed (err_mask=0x100) ata2: SRST failed (status 0xFF) ata2: SRST failed (err_mask=0x100) ata2: reset failed, giving up

I installed centos 4.4 on the same machine. Then I did not get these errors. Then, I updated it to CentOS 4.5. Then also, I did not get those errors?

why does it happen to CentOS 5 ?
